eBay has confirmed that it pulled a Nike T-shirt with the words "Boston Massacre" printed on it from its online marketplace.

Nike Inc. has already pulled the T-shirts from the market.

Last week's bombing during the Boston Marathon killed three people and left dozens injured.

eBay Inc. spokeswoman Johnna Hoff said in an email Thursday that the shirt was in violation of the company's offensive materials policy. This bans items that promote hatred, violence, portray graphic violence or victims of violence, among other things.

The "Boston Massacre" phrase has been used to describe a pivotal late-season sweep by the New York Yankees of the rival Boston Red Sox in 1978. That season culminated in a World Series baseball championship for the Yankees.
